+# Explanation of the `smallestEvenMultiple` Code
+
+This Java class provides a solution to calculate the smallest even multiple of a given number `n`.
+
+---
+
+## Class: `Solution`
+
+### Method: `smallestEvenMultiple(int n)`
+
+#### **Purpose**
+The method returns the smallest even multiple of the integer `n`.
+
+#### **Parameters**
+- `n`: A positive integer.
+
+#### **Logic**
+1. **Check if `n` is Even**:
+   - If `n % 2 == 0` (i.e., `n` is divisible by 2 without a remainder), then `n` is already an even number. In this case, return `n`.
+
+2. **Calculate the Smallest Even Multiple**:
+   - If `n` is odd, its smallest even multiple is `n * 2`, because multiplying any odd number by 2 produces the smallest even multiple of that number.
+
+3. **Return the Result**:
+   - Depending on the condition, either `n` or `n * 2` is returned.
+
+---
+
+### Example Execution
+#### Input:
+```java
+int n = 5;
+
+Time Complexity: O(1)
+Space Complexity: O(1)
